2 Ciaims.

My invention relates to i mprovements in catheads and more particularly tcatheads equipped with means'whereby the latter is capable of being cooled.

One of the principal objects of my invention isto provide a cathead equipped with means whereby the latter is cooled thereby eliminating excessive heat and wear to t'xe rope lines operating thereon. p I

Another object of my invention is to provide a device of the above describedcharacter which is simple in construction, durable in'use, eflicient A in operation, and economical in manufacture.

Other objects and advantages will be apparent from the following description, ap nded claims and annexed drawing.

Referring to/the drawing wherein like 'reference characters designate like parts throughout the several views:

Figure 1 is a longitudinal sectional view of my invention` }Figure 2 is a sectional view thereof taken on the line 2,-2 of Figure l.

My improved form of cathead comprises a hol- 1 low spool 5 mc unted on a rotatable shaft 6 by means -of a centrally disposed hollow tube 'I formed integral with said spool'and keyed to the' shaft G by a key 8. Onev end of the spool is closed by a wall 9 integrally connecting the latter to the `tube 1 and the opposite end is open. Said open end is sealed by means of a circular block IO having a centrally disposed aperture H through which the shaft 6 extends, said shaft being, rotatable within said aperture of the. block.

a' A packing ring l2 is mounted on the shaft between the end of the tube 'I 'and the inner face of the block ili adjacent the aperture Il whereby to effect a seal between the interior of the spool and said aperture II. The wall of the block deflning the aperture H is provided with a circumferentially extending cut. out portion 13 in which is mounted adjacent the packing ring iZ a similar packing ring Il. Within said groove |3 and outwardly of the packing ring Il there is also mounted a plate IS having a plurality of roller bearings IB mounted thereon land which engage the shaft 6. The packing ring H and plate li are secured in position within the cut out portion 13 by means of a threaded ring I 'I which engages an interiorly threaded end section of the cut out portion l3. The outer peripheral face of -the block 10 is alsofashioned with a circumferentially extending cut out portion 18 in which is mounted a packing ring I! effecting a seal between the interior of the spool and the outer portion of the block ID. Mounted in said cut out portion IO adiacent the packing ring I! is. a roller bearing assembly ill which engages the inner peripheral wall of the spool adiacent the outer open end thereof. An interiorly threaded (on. sta-m) ring Zi' is threaded on an outer circumferentially extending threaded section of the block I 0 whereby to secure the packing ring 99 and bearing assembly 20 in adjusted position.

A water inlet pipe extends into the spool through an aperture 26 formed inthe block above the shaft 6 and. is disposed subjacently and in proximity with the upper section of the inner face of the spool. Beneath the rpper section of the inner face of the spool, the water inlet pipe is provided with a perforated section 2611 for spraying water onto the inner surface of said spool. Below the shaft 6 and extending through the block ID is a water outlet pipe 21 whereby water is drained from said spool and said pipe 21 1 coacts with said pipe 25 to effect a Circulation of water within the spool. A plurality of bracemembers 28, secured to the block, extend to a desired anchorage adjacent thereto.

From the foregoing it will be apparent that I have provided a simple and efilcient device whereby a cathead is supplied with water or other suitable liquid for cooling the peripheral face thereof thereby eliminating excessive heat and wear on the rope lines Operating thereover.

I claim: A,

1. A device of the character described, comprising, a hollow spool having opened and closed ends, a centrally disposed tube extending therethrough and integrally connected to said closed end, said tube adapted to be secured to a drive shaft extending therethrough for' rotating said spool, a stationary block closing said opened end of said spool and equipped with packing rings eifecting seals about said shaft and said open end, and a supply pipe extending through said block and spool and lhaving an apertured section extending in parallism and in close proximity to the inner face of said spool whereby to cool said inner face when liquid is discharged through said apertures.

2. A device of the character describe'd, comprising, a hollow spool having opened and closed ends, a centrally disposed tube extending therethrough and integrally connected to said closed end, said tube adapted to be secured to a drive shaft extendingv therethrough for rotating said spool, a stationaxy block closing said opened-end of said spool and equipped with packing ringsl effecting seals about said shaft and said opened end, a supply pipe extending through said block and spool and having an apertured section extending in parallelism and in close proximity to the inner face of said spool whereby to cool said inner face when liquid is discharged through said apertures, and a liquid return pipe extending into said spool through said block and terminating adjacent said tube whereby to' effect a circulation of said liquid within said spool.
